When do you all start letting newborn sleep alone in the room

in my opinion, wait for at least 3 months or so when baby starts sleeping through the night. 1 month old still wakes up every 1-2 hrs for milk. it'll be troublesome to go back and forth for that. i let my baby sleep in her cot since newborn (now one month old) and she's getting used to being independent sleeping alone, but she is still near me for easy feeding and monitoring.
